Problem analysis: Hello, less menstrual flow can be considered from the reasons of excess and deficiency. First, my physical condition is poor, or I have malnutrition diseases such as anemia, so my menstruation is naturally short and short, which belongs to deficiency. This situation needs to treat anemia and other primary diseases, supplement nutrition and enhance physical fitness.

Suggestion: Second, getting cold before menstruation, being in a bad mood, eating spicy food and other factors lead to poor menstrual discharge, which is a real aspect. Treatment can take drugs such as Xinshenghua Granule, Qizhi Xiangfu Pill, Xuefu Zhuyu Pill to regulate and promote the elimination of blood stasis. So I suggest you go to the hospital for treatment after a clear diagnosis.
